The Helicoil HELR4649-12 is a high-quality thread repair solution designed for 12mm (0.472 inches) threads with a pitch of 1.25. This product is manufactured by Helicoil, a renowned brand in the thread repair industry, known for its innovative and durable solutions.

The HELR4649-12 is specifically engineered for use in 12mm NF (National Fine) threads, which are commonly found in various industrial, automotive, and mechanical applications. The "NF" designation indicates that the thread pitch is finer than standard threads, making this Helicoil product an ideal choice for repairing such threads.

The Helicoil thread repair insert features a unique helix design. This design allows the insert to be installed into damaged or worn threads, effectively restoring the thread's original strength and functionality. The insert is made of a high-tensile, alloy steel material, which provides excellent resistance to wear, corrosion, and seizing, ensuring a long-lasting repair.

To install the Helicoil HELR4649-12, you will need a Helicoil installation tool, which is not included in the package. The installation process involves driving the Helicoil insert into the damaged thread using the appropriate installation tool. The tool applies a controlled force to the insert, ensuring a precise fit and proper engagement with the existing thread.

* Repairing damaged threads on engine components, such as cylinder heads, manifolds, and transmission cases

* Fixing threads on automotive components, such as wheel studs, brake calipers, and exhaust system components

In conclusion, the Helicoil HELR4649-12 is a versatile and reliable thread repair solution for 12mm NF threads. Its unique helix design, high-tensile steel material, and compatibility with a wide range of applications make it an essential tool for anyone involved in industrial, automotive, or mechanical repair work.
